Proof mass is the inertial reference element in accelerometers that converts acceleration into measurable displacement or force.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Mass | 1mg to 100g | |
| Density | 7.8-19.3 g/cm³ | |
| Symmetry | >99.5% | |
| Tolerance | ±0.5-5μm | |
| Surface Finish | Ra 0.1-0.8μm | |
| Resonant Frequency | 500Hz-50kHz |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.

Manufacturer profiles associated with Proof Mass.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Higher density materials provide greater inertial force for the same volume, increasing sensitivity and signal-to-noise ratio while allowing miniaturization.
Mass value determines sensitivity, geometry affects frequency response and cross-axis sensitivity, material properties influence thermal stability, and manufacturing precision impacts measurement accuracy.
Machining (for macro-scale), MEMS fabrication (for micro-scale), EDM, precision grinding, and laser micromachining, depending on size, material, and tolerance requirements.
